Has anyone with a '99 or newer Mustang had a problem with fogging, condensation, or a film build up on the inside of their headlight assemblies? I checked the NHTSA TSB database and saw nothing. I was at a show this month and a couple of different people told me they had the problem too.

My dealer is ordering me new headlight assemblies and will replace them under warranty but said I shouldn't be surprised if it occurs again. The body shop manager said they've replaced them on a number of other vehicles and not just Mustangs. They mentioned something about the assemblies not being properly manufactured or sealed during the manufacturing process.

Has anyone else had this problem and if you did, have you had it corrected? Any other things I should consider doing once they're replaced to prevent it from happening again?

Good one.

Yes, I have heard of the fogging issue from many folks. I, personally, have not experienced it yet. However, with the fall/winter season rapidly approaching, it may rear its ugly head soon. Not to imply that it is related to cold weather or anything, just wondering...

At least they are replacing the light assemblies under warranty. I count that as a positive.

Anyone else?

I haven't heard of this for the newer ones yet. I'll have to keep an eye on my '99. I know the older ones, particularly the Fox-bodies seem to regularly have that problem now. I just figured it had to do with age.

If it happens to mine, that'll be the perfect opportunity to get those cool smoked headlights from the '01s!

I been dealing with this on Bullitt 1007. 1007's have been replaced aready, it was covered under the Bumper to bumper....
I have yet to see a 99 and 2000 model year clear lense fogged. I've seen numerous tinted lens fogged on 2001 Bullitts and GT's. Seems to be worse on the right lens.
I have a friend with a 2001 Cobra with 15000 miles and his are perfect.
Scott Hoag said that it is believed it's not water causing the fogging but the Glue vapor from the assmembly of the lens. 1007 went months without a problem but one day I noticed it and it continuly got worse....
I've heard rumor that new and improved light assmemblies are being made that won't fogg. Hopefully 1007 got those when the dealer replaced the Fogged ones.

D'Oh! I noticed spots on the inside of my Bullitt's headlamps the other day. I haven't gotten back by the dealership with it yet. It does look like spotting caused from glue vapors. If you have ever Superglued clear pastic, you know what I mean.

No problems yet with my 2001 Cobra but I will keep an eye out. Thanks for the warning.

My Bullitt's been at our storage garage since the end of September. We'll be bringing it home this weekend and I'll check out the headlights. I've also been reading about this problem (and others!) on the Bullitt forum.
I can't stand my local ford dealership so will probably have to travel 45-60 miles to get the job done without wanting to nuke someone!
We also have the early chip that supposedly causes pinging, might as well get that changed and the tranny check out too since they are also problematic - even though we haven't experienced any trouble yet!

Hey J, what's up with the chips and the trannies? I hadn't heard anything about those yet.

Joyce,
1007 has the early chip and NO problems.... Also the trany clucking problem I think is the driver, Only time 1007 does it when I'm doing something stupid. I think it is the lash in the drive line everyone is hearing. Which to me is normal. But I could be wrong.

Hi Jimmy Ray,
No. 1004 hasn't had any of those mentioned problems either - ours must have been made on the same day. Today I looked very closely at the headlights and they are not clouded or spotted either.
Those potential problems are some mentioned by others on the Bullittclub forum.
I guess problems mentioned get more attention and remain in memory more than the problem free cars.
But still, there is the potential and there are either recalls or notices put out about them by Ford.
My Bullitt is now in winter storage and we didn't take it in for any adjustments. No sense messing where there's no reason. "If it ain't broke..."

J,
I had the spotted head lights, but service department took care of it quick... And I had the heater/AC fan go out and that was also quickly fixed... Other wise 1007 is a stud....

As an FYI, here's what I've been told when both my headlight assemblies were replaced -

They use a crazy-glue like adhesive to join the parts of the headlight assemblies together and seal them. If during production the glue residue gets on the inside of the assembly (e.g., fingerprints of the assembler), eventually the spots will start to show up with temperature and humidity fluctuations.

Another source for the condition can occur from a buildup of vapor from the glue on the inside of the assembly, which can cause the haze or fogging on the inside of it.

My guess is that if you live in an area where dampness or high humidity can be an issue, or when wide seasonal temperature fluctuations are the norm, that the likelihood you will experience this will increase. My dealer told me they've experienced this on Crown Vics, Tauruses, and Windstars too. They also said don't be surprised if it occurs again and the units have to be swapped a second time (again at no charge of course).

I hope this information is of use to other M&Mers out there.

Wishing everyone a pleasant and safe holiday season!
